1. The problem statement, all variables and given/known data given: Vn+1=Vn*cos(pi/2^(n+2)) 2. Relevant equations Write a sequence Vn in terms of n 3. The attempt at a solution we substitute n with n-1 and we get: V(n-1)+1= Vn-1*cos(pi/2^(n-1+2)) Vn=Vn-1*cos(pi/2^(n+1) Is this correct?
Alright it was an extra credit question in class just wanted to make sure if it was correct. Thank you very much.
I mostly use the LaTeX from the Forums. To check my code I sometimes use mimeTeX online. Do a search in these Forums.
Yea i have them, but when i type up something in there and I try putting it up in here it comes up all weird.
Oh, I didn't understand that's what you wanted to do. What problem are you having using the forum TeX tools for the forum?
It's not a 'problem' but sometimes when I want to type something in it doesn't come up how I want it. This is an example with Lyx: U_{n+1}=V_{n}+U_{n}
I'm confused. That is an example of what with Lyx?[tex]U_{n+1}=V_{n}+U_{n}[/tex] displays OK here with tex tags.
You have to enclose tex expressions with tex or itex tags. They are like the $$ or $ tags in regular tex. Right click on the expression to see the source. [Edit] Woops, that doesn't show the tags. Start to reply with a quote to the post with the tex and you will see the tex tags. It's like this: [tox]Put your tex here[/tox] and use tex instead of tox. (If I use tex you won't see the tags).
Yep. You can use itex for inline and you can preview your posts before you submit them to see it's all OK.
